The research approach used is a quantitative research approach with the Vector Auto Regression (VAR) analysis technique of the VECM model supported by Stationarity Test, Model Stability Test, Optimal Lag Length Test, Granger Causality Test, Cointegration Test, Impulse Response Function Test, and Variance Decomposition Test. assisted by Software Eviews 9. This study uses a sample from 2015 to 2020.

In the short term, the GDP variable has a positive and significant effect on inflation. Based on the Impulse Response Function (IRF) analysis, all variables in the short term have a stable response and experience few shocks and based on the Forecast Error Variance Decomposition (FEVD) analysis, the GDP variable is the variable that has the largest response and the largest composition compared to other variables.
